Abstract
An instrument having a liquid crystal display disposed behind a glass cover and separated from the cover by a hollow space. The hollow space is filled with an immersion medium to which is added a substance imparting thixotropic properties to the immersion medium. The added substance has a refractive index comparable to that of the immersion medium.
